The Miami Dolphins are in year four of the Ryan Tannehill and Joe Philbin quarterback and head coach pairing, and it can be the last chance they have together to make the playoffs before major changes are made.

The Dolphins tried to help Tannehill and the offense by signing Mike Wallace to a big deal during the free agency of 2013, but the team is moving on with the failed experiment when Wallace was dealt to the Minnesota Vikings for barely anything in return. Veteran wide receivers Brian Hartline and Brandon Gibson were not brought back for 2015, as the offense goes through a makeover at the skill positions.

Kenny Stills was brought in from the New Orleans Saints in a trade for linebacker Dannell Ellerbe, which creates some cap flexibility for the team. Along with Stills, the Dolphins are banking on the improved production of second-year wide receiver Jarvis Landry, who caught 84 passes for over 750 yards and five touchdowns in his rookie campaign. Lastly, the Dolphins swapped tight ends, signing Jordan Cameron from the Cleveland Browns and moving on from Charles Clay, who went to the Buffalo Bills.

The largest splash signing was acquiring defensive tackle Ndamukong Suh for $60 million guaranteed. The Dolphins have above average edge pass rushers and solve a huge need in the middle of their defense. They have a focal point of their defense for years to come, as Suh is one of the most dominant lineman, if not the most dominant, in the entire NFL. The Dolphins also signed cornerback Brice McCain, who will have the second cornerback spot behind Brent Grimes, the young rising superstar in Miami’s secondary.

Both lines on the offensive and defensive side of the ball remain mainly intact, with the rather large addition of Suh, along with a linebacker unit that sees many similar faces besides the replacement of Ellerbe. The Dolphins are banking on Tannehill having better chemistry with the new skill position players than the past.
